Title: Externally applied rf for pulmonary vein isolation
Inventor: SCHWARTZ YITZHACK
IPC: A61B5/296
Filed: 2004-11-08
Abstract: A resonant circuit is incorporated in a stent, which implantable in a pulmonary vein using known cardiac catheterization techniques. When an external RF field is generated at the resonant frequency of the stent, RF energy is re-radiated by the stent toward electroconductive tissue in the wall of the pulmonary vein, and produces a circumferential conduction block. The stent can be made of biodegradable materials, so that it eventually is resorbed. Following an ablation procedure, the stent may be left in situ. Repeated ablation can be performed using the inserted stent until it has been determined that the desired lesions have been formed. Furthermore, the same stent can potentially be used even years after being inserted should the treated arrhythmia reoccur or a new arrhythmia develop, thereby possibly obviating the need for an invasive procedure at that future time.

Title: Heat sink having folded fin heat exchanger core
Inventor: TABAN VAHID
IPC: H01L23/467
Filed: 2003-08-19
Abstract: A heat exchanger core (30) for a heat sink having a plurality of folded heat conductive fins (1-1...1-25). Each folded heat conducting fin (1-1) has a front face (3-1), a back face (5-1) spaced from the front face, a top (9-1) connected between the front and back faces, open opposite sides that communicate with the atmosphere, and an air intake opening (20-1) that extends vertically through the top (9-1) for receipt of a supply of fan blown air. The fins (1-1...1-25) are arranged face-to-face one another to establish laterally extending primary (7-1) and supplemental (24-1) air exhaust cavities through the heat exchanger core (30) which run between the vertically extending air intake openings (20-1...20-25) and the open opposite sides of the fins. Thus, the heat exchanger core (30) will have non-linear air flow paths by which heat collected by the plurality of fins (1-1...1-25) is blown into the atmosphere at the open opposite sides thereof. By virtue of the foregoing, the heat exchanger core (30) provides maximum surface area, efficient heat transfer, and optimal air flow so that the heat generated by a source (e.g. a CPU) can be effectively collected and exhausted to the atmosphere.

Abstract: L'invention concerne des séparateurs pour des batteries au lithium, ainsi qu'un procédé pour leur production et leur utilisation. Les séparateurs pour batteries au lithium selon l'invention ont pour base un substrat souple, plan et pourvu d'une multitude d'ouvertures. Un revêtement poreux, inorganique et isolant électrique est appliqué sur et dans ce substrat et ferme les ouvertures du substrat. Le matériau du substrat est sélectionné parmi des fibres polymères tissées ou non tissées, ne conduisant pas l'électricité, et le revêtement inorganique électroconducteur présente des particules d'oxyde métallique. Les séparateurs selon l'invention se caractérisent en ce qu'ils présentent des propriétés conductrices d'ions lithium en l'absence d'électrolyte. Après chargement avec un électrolyte supplémentaire conducteur d'ions lithium, on obtient une conduction ionique sensiblement supérieure à celle obtenue pour des combinaisons traditionnelles constituées de séparateurs non conducteurs d'ions et d'un électrolyte. Les séparateurs selon l'invention peuvent tout particulièrement être mis en oeuvre dans des batteries de grande capacité au lithium.

IPC: C10G53/02

Abstract: Method and apparatus for treating an ore comprising mineral substrate particles surrounded by hydrocarbon compounds, especially tar sand grains, to recover a hydrocarbon portion and a substrate portion. The ore may be comminuted as needed and mixed with water to form a slurry, which may also contain alkali, for example, sodium hydroxide. The slurry is heated to about 80°C and is intensively sheared to condition the slurry for separation by shear-fracture of the hydrocarbon layers surrounding the particles in the grains. The slurry is blended with a peroxide which enters the grains and is decomposed therein, creating bubbles of free oxygen within the grains which disrupt the hydrocarbon envelope and release hydrocarbons from the particles. The resulting hydrocarbon globules are separated from the particles by flotation, accelerated by the attached oxygen bubbles. Alkali and/or peroxide may be added during the flotation process. Tailings from the process are suitable for landfill.
